VALVE-seams COMPRESSOR.

Application filed April 6,

This invention relates to spring compressors and its general object isto provide a spring compressor and holding device for use in removingand replacing valves of the poppet type in internal combustion motors inan easy and expeditious manner with very little effort.

A further object of the invention is to provide a valve springcompressor oi the character set forth that is simple in construction,inexpensive to manufacture and ei'licient in operation and service.

This invention also consists in certain other features of constructionand in the co1nbination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims. a

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is side elevation of the device forming the subject matter ofthe. present invention, and showing the same in operative position.

Figure 2 is a fragmentary view partly in section and showing one size ofspring tool secured in the device.

Figure 3 is a detail view of a spring tool having a shank that isshorter than the shank of the spring tool shown in Figure 2.

Referring to the drawings in detail, the letter A indicates the top of awork bench to which the device is to be secured as clearly shown inFigure 1. The device includes a body having a base 1 provided withopenings to accommodate bolts 2 whereby the device is secured to thebench, and rising from the base 1 is an upright 3 disposed at aninclination and has formed therewith a web 4 which is likewise formedwith said base as shown. Extending laterally from the web 4 adjacent itsupper end is an extension 5 which terminates at its outer end in abearing sleeve 6. Disposed in parallelism with the extension 5 andformed with the upper end of the web 4 is a fork 7 pivotally receivingone end of a handle 8 through the medium of a pivot pin 9. The handlehas formed on its upper surface a plurality of teeth 10 for a purposewhich will be presently apparent. Depending from'the handle and disposedad- 1928. Serial No. 287,335.

bearing sleeve and has provided in its lower end a bore 14 for thepurpose'o f receiving the shanks 15 of spring tools 16; 1

The shanks 15 of the spring tools 16 are swiveled to the bight portionsthereofand it will be noted that these spring tools are substantiallyU-shape in formation tor the purpose of engagingthe valve stem' cup upondiametrically opposite sides thereof in the operation of the tool asshown'in Figure 1 which illustrates the tool in use, and it will beobvious that when the valve spring is compressed so as to relieve thepressure of the cup against the pin or washer-"which is secured to thestem, the pin or washer can be removed with very little efiort so thatthe valve can be likewise removed. .01:- course the parts are to bereplaced when the spring is compressed and in order to hold the springin compressed position, Iprovide a latch arm 17 which has one endpivotally secured while its opposite end is engageable in one of theteeth of the handle as shown,

From the above description and disclosure of the drawings, it will beobvious that I have provided a spring compressing devicethat is capablefor use in removing and replacing valves in internal combustion motors,and the head. of the motor can be disposed 011 the bench A and thedevice put in operation as above described. By employing the use ofvalve tools having various lengths of shanks, various types of motorscan be operated upon and these shanks are held in the bore of theplunger rod through the instrumentality of a set screw 18 as clearlyshown in Figure 2.

It is thought from the foregoing descrip- I tion that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood. that I may make changesin the constructionand in the combination and arrangement-of the several parts, providedthat such changesfall within the scope of the appended claims- What Iclaim is 1. A springflcompressor of the character described comprising abase, an upright formed with said base, a web formed with said base andupright respectively, an exten- SlOIl formed with sald web, a bearingsleeve on said extension, a plunger mounted for movement in said bearingsleeve and being provided with a bore, a handle having pivotalconnection with said web and with said plunger respectively, asubstantially U- shaped member providing a spring tool, and a shankformed with said U-shaped member and being detachably secured in thebore of said plunger.

2. A spring compressor of the character described comprising a base, anupright formed with said base, a web formed with said upright, anextension projecting from said web adjacent the upper end thereof, abearing sleeve formed with said extension, a plunger mounted formovement through said bearing sleeve and having a longitudinal boreformed in its lower end portion, a toothed handle having pivotalconnection with said web and plunger respectively, a spring tool ofU-shaped formation and includingashank, means for detachably securingthe shank in the bore, and a latch arm cooperating with said teeth forthe purpose specified.

3. A spring compressor of the character described comprising a base,means for securing said base to abench an upright formed with said base,a web formed with said upright and base respectively, a bearing sleevehaving connection with said web, a fork formed with said web anddisposed above said bearing sleeve, a handle having one end pivotallysecured in said fork, a plunger mounted for movement in said bearingsleeve, a link pivotally connecting the handle with said plunger,a'U-shaped spring tool, a shank swiveled to said tool and beingdetachably secured to said plunger, and a latch arm pivotally secured tosaid upright and cooperating with teeth formed in the handle.

In testimony whereof I afiix my signature.

ALVIN JONES.
